DESCRIPTION

an explanation will be printed to stderr, obtained from the explain_statfs(3) function,
and then the process terminates by calling exit(EXIT_FAILURE).
The explain_statfs_on_error function is used to call the statfs(2) system call. On failure
an explanation will be printed to stderr, obtained from the explain_statfs(3) function,
but still returns to the caller.

data The data, exactly as to be passed to the statfs(2) system call.
RETURN VALUE

mation. On failure, prints an explanation and exits, it does not return.
The explain_statfs_on_error function always returns the value return by the wrapped
statfs(2) system call.

lowing example:
